DYElNc-MACHINE.

SPECIFICATION forming part of Letters Patent No. 505,471, datedSeptember 26, 1893. Application iilcd December 29, 1891. Serial No.416,496. (No model.)

To all whom it may concern.:

Be it known that I, JOSEPH H. LoEIMEn, of Philadelphia, county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inDyeing and Securing Machines, of which the following is a specification.

My invention relates to dyeing and scouring machines and consists ofcertain improvements which are fully set forth in the followingspecification and are shown in the accompanying drawings which form apart thereof.

It is the object of my invention to accomplish an even and uniformdyeing of skeins of yarn, doc., without employing complicated mechanismfor the purpose of intermittently raising and lowering the skeinsupporting frames and moving the yarn thereon.

In the dyeing of yarn in the skein, the usual method employed is that ofhand dyeing, in which the yarn is moved through the dye liquor in a tankor vat by hand operation.l This method is both expensive and slow.Machines have been designed to accomplish the dyeing mechanically, bymoving the skein supporting frame through the liquor and intermittentlyturning the yarn supportingk sticks so as to change the position of theskeins thereon. An objection with this process is that the yarn issubjected to considerable movement which tends to fret the fibers andoften results in the breaking or tearing of the skeins.

In carrying out my invention, I propose to allow the yarn supportingframe to remain in the liquor and to accomplish the dyeing bycirculating the liquor through the yarn. By this means an excessiveworking of the yarn is avoided. Whenever desired the yarn may be movedby turning the supporting sticks.

My apparatus may be used either for hot or cold dyeing as is hereinaftermore fully set out.

My invention also relates to certain improvements in the construction ofthe dye vat and supporting frame and to other improvecombinations ofparts which are hereinafter more fully set out and claimed.

In the drawings: Figure lis a longitudinal vertical sectional view of myimproved dye vat and yarn supporting frame. Fig. 2 is a transversesectionalview of the same on the line y-y of Fig. l. Fig. 3 is a similarview rspective view of a on the line .fr-:c of Fig. l. Fig. 4. is aperportion of the support for the upper sticks. Fig. 5 is a similar viewof a portion of the support for the lower sticks. Fig. Gis alongitudinal sectional View of aportion of the yarn supporting frameshown in Fig. l illustrating the manner of adjusting the lowersupporting sticks. Fig. 7 is an end elevation of a modification of thesupport for the lower sticks. Fig. 8 is a vertical sectional view of thesame on the line z -z of Fig. 7. Fig. 9 is a side elevation of theapparatus for raising and loweringthe yarn supporting frame and Fig. l0is a transverse vertical sectional view of the vat illustrating thecirculation of the liquor in the process of dyeing.

A is the vat which may be of any convenient shape.

B is the yarn supporting frame consisting preferably of the vertical endpieces B', B', intermediate piece B2 and the top and bottom longitudinalpieces C, C.

Arranged transversely to the end pieces B', B', are the upper sticksupport frame D and the lower stick support frame E. For convenience ofconstruction and operation and to avoid the use of long yarn sticks, Iiind it preferable to` employ two sets of upper and lower sticks withsuitable supports therefor at the middle portion of the frame.

E is the support frame for the lower set of sticks at the middle of theframe.

F is a frame corresponding to the lower support frame E arranged at thetop of the vat and at the middle thereof, provided with bearings f, inwhich is journaled a series of worm wheels G provided with angular orirregular sockets g for the ends of the upper yarn sticks H.

G is a shaft carried in bearings of the frame F extending over the wormwheels G and provided with worms a engaging therewith. The shaft G maybe turned by a handle I, thus rotating all of the yarn sticks H.

To accomplish the movement of adjacent portions of successive skeins inthe same direction, the Worms G are arranged with threads winding inopposite directions as shown in Figs. 2 and 3. The upper support framesD are provided with a series of bearings d (preferably cup shaped asshown) to IOC receive the round ends of the sticks H and to permit thesame to be turned thereon when the yarn sticks are rotated by the wormsct and worm wheels G as heretofore described.

J is a sliding bar carried by the support frame D and free to be movedslightly in a longitudinal direction thereon by the slots j (see Fig.3). This sliding bar J is provided with a series of projections orflanges .I which are adapted to be moved over the ends of the sticks Hwhile resting in the bearings CZ to lock them therein. By sliding thebar back these projections J are moved from over the ends of the sticks,which may then be removed. By this sliding bar J with its projections Ja very convenient means is provided for locking all of the sticks inplace and of releasing them again when desired. The lower support framesE and E are similarly provided with a series of sockets c and c toreceive the ends 7e of the lower yarn sticks K.

L is a sliding bar similar to the bar J provided with projections L forlocking the ends of the lower sticks in their sockets or supports orreleasing them therefrom when desired.

The upper yarn sticks II are preferably round or rectangular in crosssection, while -I prefer to make theloweryarn sticks K of considerablewidth as shown with .the projections 7i: by which it is received at thesupports adjacent t0 its edge; so that the yarn lstick may be turnedwith reference to the projections 7@ as shown in Fig. 1, or down asshown in Fig. 6. By this means the distance between the edges of theupperand lower sticks maybe adjusted tosuit the size of the skeins. InFigs. 7 and 8, I have shown, however, a modification of the means foradjusting the sticks for different sizes of skeins. In thisconstruction, the ordinary round or rectangular sticks may be employedwith the support frames E made with two or more series of holes c e2located one below the other, and the sticks may be passed through eitherset of holes, the other ends being received in corresponding sockets e3in the frame E. A sliding bar J is employed having arms j which may bemoved over the holes c', e2, to lock the sticks against movement intheir sockets.

M is a bararranged transversely across the ends of the yarn supportingframe to keep the yarn upon the sticks from moving down upon the endsthereof.

N, N are arms hinged upon the ends of the vat A provided with supports nwhich are adapted to receive hooks() upon the frame B and support it ina raised position out of the liquor. The arms N, N, are hinged so thatthey may be turned down out of the way as shown in full lines in Fig. l,where the frame is lowered into the vat. These arms N, N, are preferablyhinged at o adjacent to the outer edge of the vat and are provided withflat bases P which are adapted to rest upon the fiat surface of the edgeof the vat and to be supported thereby.

For producing the circulation of the liquor whereby it is made to moveamong the fibers of the yarn and the movement of the yarn through theliquor is avoided, I employ a pipe Q which enters the vat and isprovided with two branch pipes R arranged longitudinally in the vat andat a distance from the sides thereof (see Figs. 2 and 3). These pipes Rare provided with lateral perforations r opening from their sides. Forhot or steam dyeing, the vat is filled with the liquor and steam isintroduced into the pipes R, R, from the pipe Q. The steam issuing fromthe lateral surfaces of the pipes seeks an escape in the surface of theliquor as is shown by the arrows in Fig. l0. This movement or circu`lation of the liquor causes it to pass through and among the fibers ofthe yarn and thus produces a perfect saturation with the dye liquorwithout the necessity of moving the yarn. When it is desired to exposethe saturated yarn to the atmosphere, the yarn supporting frame israised and is supported by the arms N, N. Once or twice orat intervals,while the yarn is in process of dyeing, the sticks Il may be turned tomove the skeins upon their supports. The particular location of thepipes R, R, may be varied if desired. For cold dyeing, I induce thecirculation by means of a vpump S (shown in dotted lines in Fig. 10). Atthe top of the vat is an outlet or overflow pipe T connected with thesuction side of the pump by a pipe t, and the pipe Q is connected by apipe s with the pressure side, so that the -dye liquor is forced by thepump through the pipe Q into the pipes R, R, and is taken out againthrough the pipeT being thus circulated through the vat. The apparatusmay thus be used either for steam or cold dyeing, by simplydisconnecting or using the pump S.

In Fig. 9 is shown the manner in which I prefer to raise and lower theyarn supporting frames into and from the vat by means of a hydrauliclift U, which carries a rotary arm or crane V to which the creel may beattached by a chain W or otherwise as desired. As shown a single liftmay be used with two or more vats.

While I prefer the details of construction here shown, I do not limit myinvention to them as it is apparent that these details may be variedwithout materially departing from the invention.
